进行搜索查询,只有匹配最多的单词才能返回post_ID

我创建了一个带有选择输入的表单,所以当用户输入德里机场作为选择位置而agra作为放置位置时,它应该返回post_ID = 2,但我使用WHERE LIKE进行了查询结果所有ID都在post_title中有“德里”字样。

这里的任何人都可以帮助我获得准确的结果吗?

提前致谢。

对于产品1:

post_ID = 1
column name | Value
post_title | Delhi, Agra //syntax pick location, drop location
post_name | delhi-agra //syntax pick location-drop location

对于产品2:

post_ID = 2
column name | Value
post_title | Delhi Airport, Agra
post_name | delhi-airport-agra 

这里的德里,德里机场和阿格拉是各种商业变化的组合。

查询:

global $wpdb;

$q1 = $wpdb->get_results("select * from table_name where post_type='product_variation' and post_title like '%".$pick[0]."%, %".$drop[0]."%'");

我知道这个查询会被更改,但我不确定应该使用哪种方法来获取我想要的ID。

1 个答案:

答案 0 :(得分:0)

$search_query = $_POST['the_search_query']; //... Get search query, be sure to validate

//... Connect to Database, then:
$results = array();
$stmt = $dbc->prepare("SELECT item_id, other_stuff FROM tablename WHERE MATCH(item_title) AGAINST(? IN NATURAL LANGUAGE MODE) LIMIT 5");
$stmt->bind_param('s', $search_query);
$stmt->execute();
$stmt->store_result();
if (($n_res = $stmt->num_rows) > 0): // $n_res can tell you how many results are found
    $stmt->bind_result($item_id, $other_stuff);
    while ($row = $stmt->fetch()):
        $results[] = array($item_id, htmlspecialchars($other_stuff));
    endwhile;
    $stmt->free_result();
else:
    echo 'error';
endif;
$stmt->close();
$dbc->close();

显示结果示例

<?php
if ($results):
    ?><ul><?php
    foreach($results as $r):
        ?><li><?php echo $r[0].' '.$r[1]; ?></li><?php
    endforeach;
    ?></ul><?php
endif;
?>

使用MATCH()AGAINST()时,您可能需要在表中添加一个FULLTEXT KEY,例如:

CREATE TABLE something (
    ...,
    ...,
    FULLTEXT KEY items_i_want_to_match (item_title, other_stuff)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
